[Provisional] Access Control Backends plugins

[OmarIthawi]

Summary

In late 2019 I’ve proposed a method to customize the access control in Open edX via plugins. This proposal is concerned about augmenting the course load and enroll permissions by providing django app and registering it using the Django settings.

Provisional status of this pull request

Due to timeline complexities, we've chosen to build a Hawthorn-specific implementation that made no use of Birdgekeeper which was introduced in OEP-09 and the permissions ADR.

Due to the timeline issues above the work was merged in our fork: appsembler#491 which enabled us to make the course-access-groups plugin.

I'm opening this pull request to probe the tests and try to see if it works on Juniper.

Next steps

I've opened a thread to discuss how can we streamline the extension point possibly in relation with Bridgekeeper. Let's discuss this on the following topic:

• Juniper update for: Pluggable access control
